Following a massive $155m renovation, the cruise ship Carnival Sunshine set sail in May with a new waterpark designed and installed by Polin Waterparks and Pool Systems.

The ship's massive new WaterWorks waterpark sports a racing theme and covers 1,500sq.m.

WaterWorks includes three spectacular slides and an aqua play structure with 40 different interactive water features. Among them is the PowerDrencher, a 300-gallon drenching bucket – the signature feature of the SplashZone kids' water play area, which also includes twin slides called mini-racers.

The main feature is the Speedway Splash, comprised of two enclosed Aquatube slides that allow riders to race along a 72m path. Polin has designed a unique traffic light system that will determine the start of each race. The system will also display each rider's time on a scoreboard at the end to identify a winner.

A third Aquatube will be a record-breaker for the cruise line. The nearly 102m enclosed Twister slide will be the longest waterslide on any Carnival cruise ship.
